# How does the structure of the alveoli relate to its function in the lungs?

May 5, 2018

#### Explanation:

The alveoli are clusters of small sacs at the end of the bronchiole tubes.

These sacs fill with air with each inhalation.

The alveoli are surrounded by capillary beds. Both the alveoli and the capillary walls are one cell thick and allows for the diffusion of Oxygen ${O}_{2}$ and Carbon Dioxide $C {O}_{2}$ between the lung tissue and the blood.
